Create and Activate Conda

This guideline provide how to activate conda environment using Mamba before installing and using P-AIRCARS.

Create conda environment

This will create the conda environment in the conda directory.

Create conda environment

1. Setup environment variables

   Set these environment variables to make conda environment isolated from your local or system environment.

   export PYTHONNOUSERSITE=1
   unset PYTHONPATH
   

2. Create a Python 3.10 environment with compaitable C/C++ compilers:

   mamba create -n paircars_env --override-channels -c conda-forge python=3.10 gcc_linux-64=14 gxx_linux-64=14 gfortran_linux-64=14 cmake pkg-config pip
   

Activate and deactivate conda environment

1. To activate the environment:

   conda activate paircars_env
   

   Note

   For the first time, after activating conda environment, type python -c "import sys; print('\n'.join(sys.path))". This should not show any local paths. If it shows local paths, conda environment is leaking into local python environements, which may cause version conflicts.

2. To deactivate:

   conda deactivate
